Our proof is an unidentified 21-year-old from Vallejo, CA, who made a $100 bet with his friends that he could fit in a child’s swing at Blue Rock Springs Park, police said.

The man used liquid laundry detergent as lubricant to fit what we assume are very athletic (not really) thighs through the baby-sized leg holes of the swing says a spokesman for the Vallejo Fire Department. Vallejo police Sgt. Jeff Bassett added:

"He promptly became stuck, and further swelling and circulation issues made it impossible for him to get out on his own."

That's when his good pals left the man and his shinny detergent-covered legs behind (without the $100).

So, like a rodent trap for dumb people, this poor stupid guy sat there from 9 p.m. until a groundskeeper heard him screaming for help at about 6 a.m.

When firefighters finally arrived they decided the best tactic to go about freeing him was to cut the chains and then transport him to the nearest hospital still in the swing.

So adult who spent the night rocking in a child’s swing arrived at Kaiser Permanente Vallejo Medical Center, still waring his dipper-esque swing before it was cut off with a cast cutter.

The man sustained non-life threatening injuries to his body. We hope that $100 covers his medical bills.
